Embodiment 1

[0018] Embodiment 1: As shown in Figure 1, the output pipe string 3 is provided with an inner hole 3b, a connecting groove 3c at the left end, and a chamfered single tenon hole 3a is provided between the hole 3b and the connecting groove 3c. Cylindrical input mandrel 2, the middle part of which is fixed with a sleeve-shaped elastic sleeve 1, the elastic sleeve can be made of EPDM, elastic sleeve 1, input mandrel 2 and the inner hole 3b of the output pipe string All are tight interference fits, and the fit is shown in Figure 3; the left end of the input mandrel 2 is provided with a single tenon 2a that is trimmed by a cylinder, and the single tenon 2a is inserted into the single tenon hole 3a and has a clearance fit. The working process of the present invention is as follows: when the vehicle runs straight on an uneven road surface, the impact of the ground is transmitted to the damping device of the present invention through the steering transmission mechanism, and due to the d...

Embodiment 2

[0019] Embodiment 2: The single tenon and matching single tenon hole in embodiment 1 can also use the cross-shaped tenon 2a1 and the matching cross-shaped tenon hole 3a1 as shown in Figure 4, which mainly rely on the side of the cross tenon to generate rigidity contact to transmit torque from the steering wheel.

Embodiment 3

[0020] Embodiment 3: The single tenon and matching single tenon hole in embodiment 1 can also use the triangular tenon 2a2 and the matching triangular tenon hole 3a2 as shown in Figure 5, which mainly rely on the cylindrical surface of the triangular tenon and tenon hole , or the side produces rigid contact to transmit the torque of the steering wheel.

Abstract

The automobile steering column damper consists of an output pipe column and an input spindle inserted into the output pipe column with connecting elastomer in between. It features the input spindle with edge chamfered tenon in one end and the output pipe column with edge chamfered groove for clearance fitting with the tenon in the input spindle. The present invention has the advantages of reducedimpact of road to the steering mechanism and raised response of the steering system.

Description

Technical field: [0001] The invention relates to an automobile component, in particular to an automobile steering column shock absorber. Background technique: [0002] At present, the steering column and the steering gear of some vehicles are connected by pipes and shaft parts through splines, and injection molding and other processes are used to make the two reliably connected. Since this connection is rigid, the driver is driving the vehicle for a long time. Among them, the impact from the road surface is directly transmitted to the steering wheel through the steering system, and high-frequency vibration can easily cause driver fatigue; some vehicles are connected with elastic materials such as rubber with high rigidity, which can reduce the impact of the impact from the road surface on the driver. influence, but there is no better solution, resulting in poor steering followability. The inventor of this patent application has worked in the research and development of autom...
